MC79MXX
3-Terminal 0.5A Negative Voltage Regulator
Features
• No external components required
• Output current in excess of 0.5A
• Internal thermal overload
• Internal short circuit current limiting
• Output transistor safe area compensation
• Output voltages of -5V,-6V,-8V,-12V,-15V,-18Vand -24V
Description
The MC79MXX series of 3-Terminal medium current
negative voltage regulators are monolithic integrated circuits
designed as fixed voltage regulators. These regulators
employ internal current limiting, thermal shutdown and safe
area compensation making them essentially indestructible.
